Application filed February 1, 1913. Serial No. 745,715.

trated in United States Patent 953,013, is-

sued March 22, 1910, in which I employed an open annular hollow U shaped core and exhaust portsf'leading out laterally from said core. In my present preferred construction I dispense entirely with said core and arrange the exhaust ports in such manner that the exhaust steam passes out tangentially in the direction of its final flow from the rotor, thereby completely utilizing the residual velocity of said exhaust.

A further object of my invention is to provide an improved turbine having either full or part peripheral admission with exhaust at its vortical center, thereby accommodating the turbine to variations of load.

In the following drawings forming part of the application and in which similar reference symbols indicate corresponding parts in the several views, Figure 1 is a detail axial section, illustrating one embodiment of my invention; Fig. 2 is an end elevation with the end plate removed,illustrating the stator reversing chamber in its relation to the rotor, and the peripheral steam chamber divided into sections; Fig. 3 is a perspective view of the stator reversing chamber illustrated in Figs. 2, 5 and 6; Fig. 4 is a perspective view of the rotor; Fig. 5 is an enlarged detail view illustrating the stator reversing chamber, juxta-placed nozzles and rotor; Fig. 6 is a perspective view of a portion of the rotor, stator reversing chamber and nozzle ring.

Referring to the drawings :1 indicates a.

rotor secured to a'shaft 13, which extends through the heads 8 of a turbine casing 2. The periphery of the rotor is provided with a series of tangentially disposed U shaped buckets or deflecting surfaces 3, the division walls between the several buckets having a portion 12 cut away forming an annular groove in the face of the rotor.

Fig. 3 indicates a stator reversing chamber of multi-cellular ring extending around the rotor 1, comprising a series of U shaped buckets 5 having their front and back inclosing walls inclined toward each other, and being provided with semicircular openings 6 forming in combination with the annular groove 12 on the rotor a continuous annular open core. A nozzle ring 9 provided with juxta-placed nozzles 7, suitably inclined for directing the steam at an eflicient angle to the rotor, is secured to the stator reversing chamber, Fig. 3, which is also provided with suitable means for attaching it to the interior of the casing 2 in correct relation to the annular supply chamber 11.

In the operation of my invention, steam is admitted to the supply chamber 11. from which it is directed by the annular series of juxta-placed nozzles 7 to the U shaped buck ets 3 in the rotor 1. The steam upon leaving the nozzles converges and unites into an annular sheet before entering the buckets 3. This initial sheet or layer of steam is deflected and discharged, at a reduced velocity, from the U shaped buckets into the circumscribing multi cellular stator reversin chamber, Fig. 3. The steam thus discharged at reduced velocity from the rotor is directed by the stator reversing surfaces 5, to the rotor where it consolidates as a secondary layer with and is deflected by the initial steam layer simultaneously directed to the rotor buckets 3; the more rapidly flowing initial layer constituting a fluid guide for efficiently deflecting such secondary steam layer. The initial and secondary steam layers are discharged from. the rotor to the circumscribing series of stator reversing surfaces 5, by which they are re-directed as consolidated secondary and tertiary layers to the rotor; the initial steam layer simultaneously directed to the rotor buckets 3, constituting a fluid guide for efliciently deflecting such secondary layer which latter acts in turn as a fluid guide for the tertiary layer. The ini tial, secondary and tertiary steam layers are discharged from the rotor to the circumscribing series of stator reversing surfaces 5, by which they are re-directed as consolidated secondary, tertiary and quaternary layers to the rotor, Where they consolidate with the initial steam layer simultaneously directedthereto; the several concentric layers constituting the more slowly moving succeeding layers. After the four concentric layers, or as many more as may be predetermined, have been thus deflected as a consolidated body in the rotor, the last layer passes out into the exhausting chamber 19, through the opening 6, in the direction of its final flow from the rotor-being dynamically deflected therefrom by the adjacent layer of steam without the aid of any metallic guiding or deflecting means. The above'described steps are repeated during the continuous operation of my invention until all the actuating steam has been re-directed, by cyclonic inflow, a plurality of times to the rotor and finally exhausted at its vortical center.

In the above described operation, the actuating steam is directed to the several rotor surfaces 3, in a continuous tangential cyclonic inflow having the outer envelop composed of high velocity steam while the inner currents are of gradually decreasing velocity, and finally exhausting by residual velocity at the center of gyration.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is 1. In a turbine, the combination of'a rotor provided with deflecting surfaces, means for directing an inflowing body of'steam'to said surfaces, said means comprising a continuous series of convergently disposed nozzles, and an annular receiving and reversing multicellular ring, said ring provided with intercellular openings whereby said steam is exhausted at its vortical center in the direction of its final flow from said rotor.

2. In a turbine, the combination of a rotor provided with deflecting surfaces, means for directing steam currents to said rotor and a multicellular reversing chamber whereby the steam is caused to flow in a cyclonic course, and intercellular spaces with openings therein to vortically exhaust therefrom said steam in the direction of its final flow.

3. In a turbine, the combination of a rotor provided with deflecting surfaces, means for directing an inflowing-body of steam to said surfaces, said means comprising a continuous series of convergently disposed nozzles, and an annular receiving, reversing and separating multi-cellular ring, said ring provided with an annular open vortex core whereby said steam is exhausted at its vortical center in the direction of its final flow from said rotor.

4. In a turbine, the combination of a rotor provided with deflecting surfaces, means for directing a cyclonically inflowing mass of steam to said surfaces comprising steam nozzles and a multi-cellular reversing chamber having V shaped division walls between each cell, and openings in the middle of the apex of each division wall, whereby said steam is exhaustedat its vortical center.

5. In a steam turbine, the combination of a rotor provided with deflecting surfaces, means for directing initial steam currents to said surfaces, a stator reversing element having a series of hollow V shaped partitions and exhaust ports comprising gaps in the outer edge of said partitions.

6. In a steam turbine, the combination of a rotor, means for directing steam currents to said rotor, a stator reversing element comprising a series of U shaped deflecting surfaces, inclosing walls forming V shaped spaces between said deflecting surfaces and exhaust ports comprising gaps in the edges of said walls opening into said spaces; said edges corresponding to the chord of said LU shaped deflecting surfaces.

7. In a turbine, the combination of a rotor provided with deflecting surfaces, means for directing an inflowing sheet of steam to said surfaces; said means comprising a continuous series of convergently disposed nozzles, and a multicellular receiving and re-' versing element provided with an open vortex core whereby said steam is exhausted by vortical action in the direction of its final flow from said rotor.

8. In a turbine, the combination of a rotor and stator provided with tangentially disposed buckets, means for directing a continuously touching series of currents to said buckets, and semi-circular gaps in the middle portion of the axially disposed edges of the tangentially disposed walls of said buckets, said gaps constituting substantially a continuous exhaust opening.

In testimony whereof I have hereunto set my hand in the presence of two witnesses, at \Vashington, District of Columbia, this 31st day of January 1913.
